to the target host; use that common function for proxy HTTP and proxy
CONNECT

In that new function, fix this problem:

     Proxy HTTP and CONNECT: Keep trying other addresses from the DNS
     when we can't get a socket in the specified address family.  We may
     have gotten back an IPv6 address first and yet our system is not
     configured to allow IPv6 sockets.

An example host is www.ipv6.org.  The first address I get back is
an IPv6 address, but my machine may not be configured to allow an
AF_INET6 socket.

Before the fix: The apr_socket() failure was fatal.
After the fix:  When apr_socket() fails, we go to the next address from
                the resolver, successfully create a socket in the
                specified family (AF_INET), and all is well.

(an unrelated fix in this commit was to pass a server_rec in a broken
ap_log_error() call)

normal case worked OK, but due to the recursion and multiple exit points,
input bytes could go thru charset translation multiple times or not at all.

The latter is the dominant style in apache.  The only
other places they can be found (AFAIK) are mod_ssl and
mod_rewrite.

Also, since each line under a make rule is treated as a new subshell,
it's not necessary to surround the whole line in ()s.

expectations of their usage.

The reason that we should make this change now is that we have changed
the implied meaning of AP_FTYPE_HTTP_HEADER - some users of this should
be PROTOCOL while others should be CONTENT_SET.  In order to clarify it,
toss all of the bogus names and force the filter writers to make sure
they understand what they are doing.

CONTENT_SET is new (horrible name - change if you have better idea), but
it indicates that it should run between RESOURCE and PROTOCOL.
mod_deflate is the ideal CONTENT_SET filter.

The changed type names are:
CONTENT is now RESOURCE.
HTTP_HEADER is now PROTOCOL.  However, most filters that used HTTP_HEADER
may want CONTENT_SET.  (Only things like POP and HTTP belong as PROTOCOL.)

MMN bump since all filters need to be recompiled due to filter reordering.

then when any request filters are added, the connection filters will be
lost.  This fixes the proxy.

phase.  This moves us to inserting the filters in the create_request
phase.  This makes more sense, because now the protocol filters are attached
to the request as soon as possible.  Previously, some requests never
called the insert_filters phase, so they don't get the filters.  Think
redirects for reqeusts that never call insert_filters.

the complexity of trying to set the filter chain correctly, with the
side-effect of forcing us to walk the entire chain whenever we add
a filter.  Since the filter chains are small, the decrease in
complexity is worth it.
